Pakistan authorities warn of more floods as rain adds to relief urgency

Sukkur: Authorities are warning of more flooding this week in Pakistan while heavy rain has lashed victims living in makeshift camps, adding to the urgency of a massive international relief effort under way.

Pakistan's worst floods in recorded history began more than two weeks ago in the mountainous northwest and have spread throughout the country.

Around 20 million people and 160,000 square kilometers (61,776 miles) of land - about 1/5 of the country - have been affected.

Sindh irrigation minister Jam Saifullah Dharejo said Monday a dam in Sukkur, a hard hit area in Sindh province, was facing a major test of its strength as flood waters coursed down the River Indus into Pakistan's highly populated agricultural heartland.

He said, "The coming four to five days are still crucial."
